It's easy to spread germs that cause colds, flu and other serious illnesses, including whooping cough and severe acute respiratory syndrome (SARS). That is why you need to protect yourself, and take steps to avoid infecting others, according to the U.S. Centers for Disease Control and Prevention.

What You Can Do

Do your part to avoid infecting others:

Don't have close contact with people who are sick.

If you are sick, stay home.

When you cough or sneeze, cover your mouth and nose with a tissue.

Wash your hands often. Use soap and warm water and wash for at least 20 seconds. If soap and water aren't available, use an alcohol-based hand sanitizer.

Avoid touching your eyes, nose or mouth.

Clean and disinfect often-used surfaces at home, work or school -- especially when someone is sick.
